We put the contenders through much of the same rigorous testing as we do with our best gaming laptops. We tested each by playing half an hour of Overwatch on high settings—a popular game, but not too taxing—and then tested our finalists with a more graphically demanding game by playing 30 minutes of The Witcher 3 on ultra with VSync off. We also played Overwatch and Doom extensively to test how our finalists held up during longer gaming sessions.
Most gaming laptops—including budget machines—have comfortable, deep-travel keyboards that cushion your fingers during long gaming sessions. This Dell model’s blue-backlit keyboard felt crisp, snappy, and responsive but a bit shallow to us, so it was not as comfortable after a few hours of gaming or typing as some of the other laptops we tested. This isn’t a dealbreaker, but we do prefer the feel of the keyboards on the Lenovo Y530 and Asus TUF Gaming FX504GM.
Mice aimed at first-person shooters, for one, tend to feature ratcheting scroll wheels—letting you cycle through your arsenal without selecting the wrong weapon—and on-the-fly resolution switchers. The latter will help you snap-change between the broad tracking you need in a frantic shootout and the tight control for lining up a sniper shot. (Sometimes this feature is dubbed something like "sniper mode," and it may involve a dedicated button for getting granular.)
So, what’s good about the Chaos Spectrum? Well, there are a lot of things, for starters, you can go from 200 to 12,000 DPI on the fly, and that’s really impressive, do keep in mind that this isn’t just software increase, and the DPI is effectively changed across the board, you get the Spectrum lighting, something that is Logitech’s own version of RGB lighting, and you get the legendary software suite that Logitech is known and loved for. The Chaos Spectrum can be used wirelessly and wired, and just like the Ouroborus, does come with an ambidextrous design.
